Note:
• After installation is complete, use the included cable holder
to manage the power cord and USB cable.
• When installing the elite Panaboard on the stand, you can
adjust its height to 4 different levels.
When changing the height, remove the left and right screws
from the back of the elite Panaboard, and securely insert
them at the desired height. Torque (greater than 1 N-m [10
kgf-cm (9 lbf-in.)])

4 Electronic Pen Position Detection Mechanism
The electronic pen position is a detection device that mainly consists of two ultrasonic sensors (Ultrasonic Sensor 1 and Ultrasonic
Sensor 2) and one infrared sensor, equipped as shown in the following figure. These sensors receive the infrared signal and ultra-
sonic wave from the electronic pen. When the electronic pen is pressed on the screen, the electronic pen sends the infrared signal
and ultrasonic wave. This infrared signal is received by the infrared sensor and converted from the infrared signal to the electrical
signal with a cycle of 30 msec (Sig.1).
The ultrasonic signals Sig.2 and Sig.3, which are generated at the same time by the electronic pen, are received with the delay time
t1 (t2) in proportion to the distance d1 (d2) from the electronic pen to the ultrasonic sensor 1 (ultrasonic sensor 2) by the ultrasonic
sensor 1 (ultrasonic sensor 2). The elite Panaboard (Electronic Board) calculates the distance d1 (d2) using the delay times t1 and
t2. As a result, the elite Panaboard recognizes the position of the electronic pen.
